Kinematics - √√study of energy transfer as it applies to identifying actual or potential injuries
Biomechanics - √√general study of forces and their effects
mechanism of injury - √√how external energy forces in the environment are transferred to the body
Newtons 3 laws - √√1. an object in motion will stay in motion
2. force = mass x acceleration
3. for every action there is an equal and opposite reaction 5 forms of energy that exist - √√1. Mechanical- energy transfer from one object to
another in form of motion
2. thermal-heat transfer from environment to host
3. chemical- heat energy trnsfer from active chemical substances such as chlorine,
drain cleaner, acids
4. electrical- energy transfer from light socket
5. radiant- energy transfer from blast sound waves, nuclear, rays from the sn
eternal forces in trauma - √√1. deceleartion- falls and collison = sudden stop
2. acceleration- sudden onset of motion- hit by a car
3. compression- hit stationary objects; bullets; blast forces
internal forces of energy in trauma - √√stress- internal force that resists external force
solid organs good at pressure wave energy
air organs better at shear forces
4 main types of traumatic injury - √√1. blunt trauma- falls; mvc; trauma
2. penetrating- stabing; GSW
3. Thermal
4. Blast Trauma- bomb deceleration vs acceleration forces - √√-Deceleration: injury that occurs as pt slows down
acceleration injury: injury that occurs as a result of other parts of the body stopping before the organs do (concussion; shearing of aorta)
environment and pathophysiology when MOI is a fal - √√-point of impact on the body
-type of surface that is hit
-tissues ability to resist injury (bone is less flexible)
-pt pushed = more acceleration
3 impacts in a MVC - √√1. vehicle hits another object: occupant = acceleration
2. occupant collides with interior of vehicle: internal organs continue
3. internal structure collide with body
5 mechanisms of injury in a blast trauma - √√Primary: blast injury; air-filled organs
at risk to rupture
secondary: fragment injuries; puncture wounds; lacerations
tertiary: impacts with larger objectes propelled by the blast win causing blunt trauma
quaternary: heat/flame/gas and smoke
quinary: exposure to hazardous materials (radioactive) Haddon Matrix in prevention and reduction of injury - √√places emphasis on countermeasures at preventing injury more than changing human behvior such as
airbags, vehicle design and road blueprints
why is there repeated emphasis on assessment for hemorrhage through the initial
emphasis - √√uncontrolled hemorrhage is teh majore causae of preventable death
after injury
Which tool can be used to rapidly assess the level of consciousness during the A - Airway and Alertness step?
Why is it important to determine alertness along with airway? What are the components of this tool? - √√A- alert
*any below here may have compromised airway
V- verbal stimuli
P-painful stimuli
U- unresponsive
Which method of opening the airway is recommended for use in trauma? - √√Jaw thrust maneuver w/ one provider stabilizing c-spine
Assessment of airway - √√Insect for tongue obstruction; loose/missing teeth;
foreign objects;
blood, vomit, secretion;
edema
inhalation injury;
listen for gurgling/snoring/stridor;
palpate for occlusive maxillofacial bony deformity; subcutaneous emphysema
Describe the current guidelines for volume resuscitation in hemorrhagic shock. - √√2 large bore IVs
1-2L fluid warmed flui
